Description and Introduction

Low Cost Green-Mode PWM Controller for Flyback Converters Here are the factual details about part **SG6848T** from Ic-phoenix technical data files:  

### **Manufacturer:**  
Silicon General  

### **Specifications:**  
- **Type:** PWM Controller IC  
- **Topology:** Current-mode PWM controller  
- **Operating Voltage Range:** 8.5V to 30V  
- **Switching Frequency:** Adjustable (typically up to 500kHz)  
- **Output Duty Cycle:** Up to 90%  
- **Maximum Output Current:** 1A (peak)  
- **Protection Features:** Over-voltage protection (OVP), under-voltage lockout (UVLO), over-current protection (OCP)  
- **Package:** TO-220 or DIP-8  

### **Descriptions:**  
The **SG6848T** is a high-performance PWM controller designed for power supply applications, including AC/DC converters, LED drivers, and offline power supplies. It provides precise control with current-mode operation for improved stability and efficiency.  

### **Features:**  
- **Current-Mode Control:** Enhances transient response and simplifies loop compensation.  
- **Adjustable Frequency:** Allows optimization for efficiency and component size.  
- **Built-in Protections:** Includes OVP, UVLO, and OCP for reliable operation.  
- **Low Startup Current:** Reduces power consumption during startup.  
- **Soft-Start Function:** Prevents inrush current at power-up.  

This information is based solely on the available technical data for the **SG6848T**.
